Fix some bugs in fns.c, discovered in passing while doing other work.
2010-11-14 Aidan Kehoe <kehoea@parhasard.net>
* fns.c (Fnreverse):
Check that non-list sequences are writable from Lisp before
modifying them. (There's an argument that we should do this for
list sequences too, but for the moment other code (e.g. #'setcar)
doesn't.)
(mapcarX): Initialise lisp_vals_staging, lisp_vals_type
explicitly, for the sake of compile warnings. Check if
lisp_vals_staging is non-NULL when deciding whether to replace a
string's range.
(Fsome): Cross-reference to #'find-if in the doc string for this
function.
(Freduce): GCPRO accum in this function, when a key argument is
specicified it can be silently garbage-collected. When deciding
whether to iterate across a string, check whether the cursor
exceeds the byte len; while iterating, increment an integer
counter. Don't ABORT() if check_sequence_range() returns when
handed a suspicious sequence; it is legal to supply the length of
SEQUENCE as the :end keyword value, and this will provoke our
suspicions, legitimately enough. (Problems with this function
revealed by Paul Dietz' ANSI test suite, thank you Paul Dietz.)
(Freplace): Check list sequence lengths using the arguments, not
the conses we're currently looking at, thank you Paul Dietz.
